BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a multifunctional disposal apparatusfor performing disposal by incineration, drying, melting, degradation,ash melting, and the like, on an object to be disposed of, such as rawrefuse, general garbage, sludge, expanded polystyrene, and the like,produced from a manufacturing plant, a service providing facility, awholesale market, a general firm, a general store, a general house, andthe like.

2. Description of the Prior Art

Conventionally, an object to be disposed of, such as the raw refuse andthe general garbage produced from a manufacturing plant, a serviceproviding facility, a wholesale market, a general firm, a general store,a general house, and the like is directly incinerated and dried in anincinerator.

Further, an object to be disposed of, such as the sludge, is dried andthen incinerated to be land filled, and any expanded polystyrene(so-called styrene foam) is collected to be degraded by a processorhaving a dedicated compressive degradation apparatus.

However, since a general incinerator adopts a mode for forcibly sendingair to burn an object to be disposed of, repetition of the high and lowfurnace temperature by oxide combustion causes combustion smoke, and theexhaust gas containing harmful substances, such as dioxin, to beemitted. Further, since the incinerated ash obtained from combustionalso includes harmful substances, the ash generated from combustion cannot be reused.

That is, the sludge or raw refuse containing a large amount of water,the highly combustible paper or wood, the plastic bags of conveniencestores or the general plastic refuse generating a toxic gas, transparentwrap film which can be considered as a cause of generation of dioxin,plastic bottles, general burnable refuse such as expanded polystyreneare often put together in the incinerator, and a large content of waterlowers the combustion temperature, which accelerates generation ofdioxin.

There are incinerators which prohibit incineration of the plasticbottles depending on the structures of the incinerators in respectiveautonomous communities. In such a case, the plastic bottles areseparated to be collected.

It is therefore an object of the present invention to provide amultifunctional disposal apparatus having functions according to typesand post-disposal apparatus having functions according to types andpost-disposal usages of an object of disposal such as raw refuse,sludge, generated garbage or a polymer-based, object, such as expandedpolystyrene produced from houses or firms, i.e., the apparatus capableof performing disposal by (1) microbial degradation, (2) pyrolysis, (3)low-temperature drying, (4) indirect hot-air drying, (5) direct hot-airdrying, (6) carbonization, (7) incineration, (8) polymer melting and (9)ash melting. In other words, an object melting and (9) ash melting. Inother words an object of the present invention is to provide amultifunctional disposal apparatus which can dry the general garbage,the raw refuse, the sludge and others, which can not be incinerated whenthey contain a large amount of water, in the multifunction disposalapparatus to be then carbonized and incinerated irrespective of thewater content.

The air intake opening 11 bis provided to the air intake box 11 a. A filter may be provided to theair intake opening 11 b so as not to absorb dusts.

The multifunctional disposal apparatus 1 may not be embedded in the soilunder the ground 12 but the respective devices 2 to 10 may be directlyinstalled in a plant, and the like, without setting these devises 2 to10 in the the frame body 11. When directly installing the respectivedevices 2 to 10 in a plant, and the like, a heat shield plate, and thelike, may be appropriately provided around these devices since extremelyhigh heat is generated. Further, a facility for improving airpermeability may be installed.

In FIGS. 2 to 5, the detailed description will now be given as to therespective devices 2 to 10, i.e., the dry combustion furnace 2, the kilnfurnace 3, the first smoke feeding portion 4, the smoke combustionportion 5, the dust filter portion 6, the second smoke feeding portion7, the air heating portion 8, the cooling tank portion 9, the meltingdevice 10 (an incinerated ash melting device).

FIG. 2 is a partially enlarged view of the multifunctional disposalapparatus according to the present invention, showing the dry combustionfurnace and the melting device provided on the right side of themultifunctional disposal apparatus taken along the A—A line in FIG. 1 inthe enlarged manner. This apparatus 1 adopts the method for performingdisposal by adjusting a temperature of a mixed waste material (expandedpolystyrene, polymer, paper waste, raw refuse, sludge and others),melting the polystyrene and drying the raw refuse and the sludge to bethereafter incinerated.

The dry combustion furnace 2 includes a first dry chamber 15, a seconddry chamber 15 b, a third dry chamber 15 d, a fourth dry chamber 15 fand a combustion chamber (dry chamber) 17 from the top in the mentionedorder. A raw refuse/sludge input portion 13 is provided on the upperpart of the first dry chamber 15, and a general garbage input portion 14is provided on the upper part of the combustion chamber 17. Therespective dry chambers 15, 15 b, 15 d, 15 f and the combustion chamber(dry chamber) 17 may not be separately formed in multiple stages butthey may be formed as one chamber. When the respective dry chambers 15,15 b, 15 d, 15 f and the combustion chamber (dry chamber) 17 areseparately formed in multiple stages, the throughput is improved.

The raw refuse input portion 13 and the generated garbage input portion14 have input openings 13 a and 14 a which are opened in the funnel-likeshape respectively, and first opening/closing valves 13 b and 14 b andsecond opening/closing valves 13 c and 14 c are provided inside thereofas shown in FIG. 2. The first opening/closing valves 13 b and 14 b areused for moving down to the second opening/closing valves 13 c and 14 can appropriate amount of the raw refuse or sludge and the generalgarbage inputted from the input openings 13 a and 14 a. The secondopening/closing valves 13 c and 14 c inputs the raw refuse, the sludgeand the general garbage together with the first dry chamber 15 and thecombustion chamber 17.

It is needless to say that the waste material is not restricted only tothe raw refuse, sludge and others inputted to the input opening 13 a,and any burnable refuse or any other object to be disposed which hascontained a large amount of water but dried may be also included. Thegeneral garbage is not restricted to those inputted in the input opening14 a, but any dried burnable object to be disposed which hardly containswater may be also included.

The refuse having a large water content is inputted from the rawrefuse/sludge input portions 13 into the first dry chamber 15, and driedin the first combustion chamber to the fourth dry chambers 15, 15 b, 15d and 15 f in the mentioned order to be then burned in the combustionchamber 17. In addition, the refuse having no water content is notsubjected to a dry process but inputted from the general garbage inputportion 14 into the combustion chamber 17 to be burned.

Further, a plurality of dry plates 15 a so set as to be capable ofswiveling are provided on the bottom face of the first dry chamber 15.As shown in FIG. 2, the long-plate-like dry plates 15 a are provided soas to be rotatable around the shaft. When all the dry plates 15 a facethe horizontal direction, the raw refuse or the sludge can be mounted onthe dry plates 15 a. On the other hand, all the dry plates 15 a rotateto face the vertical direction, the raw refuse, the sludge and the likecan be moved down into the second dry chamber 15 from gaps between therespective dry plates 15 a.

The raw refuse, the sludge and the like mounted on the dry plates 15 aare dried by the hot air rising from the second dry chamber 15 b on thelower side of the first dry chamber 15. Of course, a gap may be formedand provided between the respective dry plates 15 a or between the dryplates 15 a and the wall surface. The dry plates 15 a can rotate 180degrees. The rear sides of the dry plates 15 a can be also used, andboth the front surface and the rear surface can serve as the dry plate.The both surfaces are alternately used to prevent the dry plates 15 afrom being distorted by heat. When the dry plates 15 a and gratingplates 15 c, 15 e and 15 g rotate 180 degrees, the raw refuse, thesludge and others can be uniformly dropped.

As similar to the first dry chamber 15, a plurality of grating plates 15c which are so set as to be capable of swiveling are provided on thebottom face of the second dry chamber 15 b; grating plates 15 e havingthe similar structures are provided in the third dry chamber 15 d; andgrating plates 15 g having the similar structures are provided in thefourth dry chamber 15 f. Of course, the respective grating plates 15 c,15 e and 15 g may have a rotatable structure or a fixed structure thatdoes not allow rotation or swiveling.

When the respective grating plates 15 c, 15 e and 15 g swivel or rotatearound the shaft, the raw refuse, the sludge and others in therespective dry chambers 15 b, 15 d and 15 f can be caused to drop in thelower dry chambers 15 d, 15 f or the combustion chamber 17.

In order to cause the raw refuse, the sludge and others to drop in thesecond dry chamber, the third dry chamber and the fourth dry chamber 15b, 15 d and 15 f, and the combustion chamber 17 in the mentioned order,providing the plural dry plates 15 a or the multiple grating plates 15c, 15 e and 5 g which are not one plate enables uniform agitation whenthe raw refuse, the sludge and others drop, thereby realizing evendrying.

As shown in FIG. 2, a width between the respective gratings is differentamong the grating plates 15 c, the grating plates 15 e and the gratingplates 15 g, namely, a gap between the gratings of the grating plates 15c is narrowest; a gap between the gratings of the grating plates 15 e islarger than a gap between the gratings of the grating plates 15 c; and agap between the gratings of the grating plates 15 g is larger than a gapbetween the gratings of the grating plate 15 e. That is because the rawrefuse, the sludge and others which fall downwards are gradually driedin the second dry chamber 15 b, the third dry chamber 15 d and thefourth dry chamber 15 f in the mentioned order as they drop. They becomefine particles having no water content, and the raw refuse, the sludgeand others dried on the top faces of the grating plates 15 c, 15 e and15 g hence pass through the space between the gratings to drop into thelower dry chambers without swiveling the dry plates.

The raw refuse, the sludge and others which have passed the first drychamber 15 to the fourth dry chamber 15 f to be dried and the generalgarbage inputted from the general garbage input portion 14 are collectedin the combustion chamber 17 provided below the fourth dry chamber 15 f.A fire grate 17 b is provided on the bottom face of the combustionchamber 17 and the refuse is mounted on the fire grate 17 b.

A heating chamber 20 for reserving the air heated by a heating burner 20a and a heat radiating tube 20 bconnected to the heating chamber 20 areprovided below the combustion chamber 17; an air leading tube 19 forsending the fresh air to the heating burner 20 a is connected to theheating burner 20 a; an exhaust tube 21 for emitting the hot air in theheat radiating tube 20 into the outside of the dry combustion furnace 2is connected to the heat radiating 20 b; and an air supplying tube 22for taking in the heated fresh air or the fresh air is connected/to thedry combustion furnace 2.

A plurality of thermal storage mediums 20 c consisting of ceramics or aheat resistant metal are provided in the heating chamber 20. When thethermal storage mediums 20 c are heated by the heating burner 20 a, theheat of the heating burner 20 a is stored. Further, when heating iscarried out beyond the capacity of the thermal storage mediums 20 c, aninfrared ray or heat is emitted so that the heating chamber 20 can bemaintained at a high temperature.

The air leading tube 19 and the exhaust tube 21 communicate with the airintake box 11 a provided to the frame body 11 of the multifunctionaldisposal apparatus 1. As shown in FIG. 5, an opening/closing valve 22 ais provided to the air supplying tube 22 and connected to both an airsupplying tube 58 of the air heating portion 8 and a air cooling tube 61of the cooling tank portion 9 so that the heated fresh air or the cooledfresh air, or the mixed air of the heated fresh air and the cooled freshair can be led into the dry combustion furnace 2.

The air supplying tube 22 for taking in the heated fresh air or thefresh air is connected because the fresh air is sent from the airleading tube 19 to the heating burner 20 a but oxygen for incinerationis hardly contained in the air heated by the heating burner 20 a. Theheat radiating tube 20 b does not directly send the air heated by theheating burner 20 a into the combustion chamber 17 but heats the freshair around the heat radiating tube 20 b by the heat radiating tube 20 bto transmit the high heat to the combustion chamber 17.

When the combustion chamber 17 is also simultaneously dried by indirectheat, the heat emitted from the heat radiating tube 20 b and the freshair can dry the refuse in the combustion chamber 17 at a hightemperature, and the hot air from the heat radiating tube 20 b and theheat for drying the refuse can dry the raw refuse or the sludge in thefirst dry chamber 15 to the fourth dry chamber 15 f.

The smoke generated by the hot air from the heat radiating tube 20 b andincineration of the refuse is exhausted to a smoke exhaust tube 29connected to the upper portion of the first dry chamber. Anopening/closing valve 29 a is provided in the middle part of the smokeleading tube 29, and the smoke leading tube 29 is connected to the kilnfurnace 3. The kiln furnace 3 may be connected to the dry combustionfurnace 2.

As shown in FIG. 3, the dry combustion furnace 2 is connected to thekiln furnace 3 through the smoke leading tube 29, and the kiln furnace 3is connected to the first smoke feeding portion 4. When the blower 39 isdriven to forcibly send the air from a tip 39 b of the air supplyingtube 39 a and a lower end 40 a of a flue 40, the inside of a cyclonefurnace 35 of the first smoke feeding portion 4 forms a vacuum, and theair or the smoke in the dry combustion furnace 2 is then absorbed in thesmoke feeding tube 29. Therefore, since the inside of the dry combustionfurnace 2 also forms a vacuum, the fresh air is absorbed from the airsupplying tube 22.

As shown in FIG. 2, a vibrator 17 a is provided to the fire grate 17 bset on the bottom of the combustion chamber 17. Upon completion ofincineration of the refuse in the combustion chamber 17, the vibrator 17a is driven to vibrate the fire grate 17 b so that the incinerated ashlying on the fire grate 17 b can be shaken off into an ash pan 17 c. Thefire grate 17 b may have a structure allowing attachment of the vibrator17 a thereto and rotation. 5 Further, a belt conveyer may be disposedinstead of the ash pan 17 c.

As shown in FIG. 2, to the lower portion of the heat radiating tube 20 bis provided a funnel fume pan 23 for collecting a funnel fume generatedfrom incineration of the refuse or a funnel fume and the like producedwhen the dry combustion furnace 2 is used as a carbonization device.

As shown in FIG. 2, doors 16, 16 a and 18 which can be opened/closed forcleaning for removing residues, maintenance, or inspection forconfirming the combustion state are provided to the first dry chamber15, the third dry chamber 15 d, the fourth dry chamber 15 f, thecombustion chamber 17 and others. There are also provided an ash accessdoor 18 a for taking in or out the ash pan 17 c and a funnel fume accessdoor 24 for taking in or out the funnel fume pan 23, and others.

Wheels and rails may be provided to the lower surfaces of the ash pan 17c, the funnel fume pan 23 and others so that the ash pan 17 c and thefunnel fume pan 23 can be taken in or out from the ash access door 18 aand the funnel fume access door 24 in order to remove the ash or thefunnel fume to the outside of the dry combustion chamber 2.

A circulation tube 30 for utilizing the combustion heat generated fromincineration of the refuse is provided to the combustion chamber 17, asshown in FIG. 2.

The circulation tube 30 is connected to the circulation tube 30 of afreezing machine 63.

The circulation tube 30 is used to drive the freezing machine 63employed in the cooling tank portion 9. That is, it permeates water anddrives the freezing machine 63 by using the high-temperature water orsteam.

As shown in FIG. 2, a belt conveyer may be provided to the inputopenings 13 a and 14 a of the raw refuse/sludge input portion 13 and thegeneral garbage input portion 14 so that the raw refuse, the sludge, thegeneral garbage and others can be automatically conveyed and inputted tothe input openings 13 a and 14 a.

All the valves 13 b, 13 c, 14 b, 14 c, 22 a and 29 a provided to the drycombustion furnace 2, all the grating plates 15 a, 15 c, 15 e and 15 g,the fire grate 17 b, the vibrator 17 a and the heating burner 20 a maybe automatically controlled by a computer and the like. Sensors fordetecting a combustion temperature, an exhaust temperature, a watercontent and others may be provided to the dry chambers 15, 15 b, 15 dand 15 f, the combustion chamber 17, the heating chamber 20 and othersto enable automatic control using the computer.

The melting device 10 is made up of an air supplying tube 25, a meltingtank 26, an exhaust tube 28 and others. A pan 26 b is provided under themelting tank 26, and a grating plate 26 a for mounting polyethylene foamor a polymer-based substance thereon is provided above the pan 26 b.

The expanded polystyrene (so-called expanded polystyrene), thepolymer-based substance and the like 27 is mounted on the top face ofthe grating plate 26 a, and the opening/closing valve 25 a provided tothe air supplying tube 25 is opened to lead the hot air supplied fromthe air heating portion 8 into the melting tank 26.

When the heat transmitted from the wall of the dry combustion furnace 2is utilized to perform fusion, only a small amount of the hot air fromthe heating portion 8 is advantageously required.

Since the led hot air has an extremely high temperature, it melts theexpanded polystyrene, the polymer substance and the like 27, and themolten liquid substance is reserved in the pan 26 b. An agglomerate ofpolystyrene which is the molten substance reserved in the pan 26 is thepolymer-based substance, and it is hence suitable to be reused.

The hot air which has molten the expanded polystyrene and thepolymer-based substance 27 passes through the exhaust tube 28 having theopening/closing valve 28 a to be fed to the second smoke feeding portion7.

As shown in FIG. 3, it is burned in the burner 50 at an extremely hightemperature and again incinerated in the cyclone furnace 48. Thereafter,it is quickly cooled down to be exhausted from a funnel draft 53 to theoutside of the second smoke feeding portion 7.

A computer and the like may be used to automatically control driving ofthe opening/closing valves 25 a and 28 a provided to the melting device10. A sensor for detecting a temperature and the like may be provided tothe melting tank 26 for allowing the automatic control using a computer.

FIG. 3 is a partially enlarged view of a multifunctional disposalapparatus according to the present invention. That is, this is anenlarged view showing the kiln furnace 3, the first smoke feedingportion 4, the smoke combustion chamber 5, the dust filter portion 6,and the second smoke feeding portion 7 provided between the A—A line andthe B—B line in FIG. 1. FIG. 4 is an enlarged view of the smokecombustion portion and the dust filter portion of the multifunctionaldisposal apparatus according to the present invention.

Referring to FIG. 3, to the smoke leading tube 29 connected to the drycombustion chamber 2 shown in FIG. 2 are continuously provided the kilnfurnace 3, the first smoke feeding portion 4, the smoke combustionportion 5, the duct filter portion 6 and the second smoke and the secondsmoke feeding portion 7 in the mentioned order.

The kiln furnace 3 is rotatably provided to a tip 31 a of the smokeleading tube 29 and one end 31 b of the cyclone furnace 35. A pluralityof rails 31 c are provided on the outer peripheral surface of acylindrical body 31 of the kiln furnace 3. There are drive wheels 31 dwhich rotate in contact with the rails 31 c of the cylindrical body 31.A storage chamber 33 is provided to the kiln furnace 3 via the tube 33a, and an opening/closing valve 34 is provided between the cyclonefurnace 35 and the kiln furnace 3. Reference numeral 32 denotes a refuseinput portion for inputting the refuse into the cylindrical body 31 ofthe kiln furnace 3. The refuse input portion 32 and the storage chamber33 for burned embers may be provided on the opposed positions on theleft and right end surfaces.

The refuse input portion 32 provided to the kiln furnace 3 has an inputopening 32 a opened in the funnel-like shape, and a firstopening/closing valve 32 b and a second opening/closing valve 32 c areprovided in the refuse input portion 32 as shown in FIG. 3. The firstopening/closing valve 32 b is used for dropping an appropriate amount ofthe raw refuse, the sludge, the general garbage and other inputted fromthe input opening 32 a into the second opening/closing valve 32 c, andthe second opening/closing valve 32 c is used for inputting the rawrefuse, the sludge, the general garbage and others into the kiln furnace3.

The cylindrical body 31 of the kiln furnace 3 is hollow, and the hot airand the smoke which flows into the rotating cylindrical body 31 and issent from the smoke leading tube 29 dry and incinerate the object to beburned such as the refuse in the kiln furnace 3. The exhaust gas, thehot air, the smoke and the flue gas generated from incineration areabsorbed into the first smoke feeding portion 4.

The burned embers obtained by drying and incinerating the object ofcombustion while being rotated in the cylindrical body 31 enter thestorage chamber 33 through the tube 33 a. The burned embers can bereused as a fertilizer and others because they are completely burned atan extremely high temperature.

Opening/closing of all the valves 29 a, 32 b, 32 c and 34 provided tothe kiln furnace 3 and rotation of the cylindrical body 31 by the drivewheels 31 d may be automatically controlled by a computer and the like.Sensors for detecting a combustion temperature, an exhaust temperature,a water content and others may be provided to the inside of thecylindrical body 31, the smoke leading tube 29 and others in order toenable automatic control using a computer.

The first smoke feeding portion 4 is made up of a cyclone furnace 35, anair leading tube 36, a burner 37, an air supplying tube 38, a blower 39,an air supplying tube 39 a and a flue 40. Since a tip of the airsupplying tube 39 a attached to the blower 39 is slightly inserted intoa tube end 40 a of the flue 40, the air supplied from a tube end 39 b ofthe air supplying tube 39 a connected to the blower 39 is blown from thelower end 40 a of the flue 40 and it is further emitted to the flue 40while taking the smoke, the hot air and others from the inside of thecyclone furnace 35 by the ejector effect. Therefore, the inside of thecyclone furnace 35 constantly forms a vacuum.

The hot air, the smoke and other s from the kiln furnace 3 are blown toa position slightly shifted from the center of the upper portion of thecyclone furnace 35 and cause the funnel fume contained in the hot air,the smoke and others to be gradually dropped into the lower portion ofthe cyclone furnace 35 while spirally rotating in the cyclone furnace35. At this time, the burner 37 attached to accelerate spiral rotationof the hot air, smoke and others reheats the funnel fume contained inthe hot air, the smoke and others so that the funnel fume is completelyburned to be nontoxic.

A vortex flow in the cyclone chamber 35 extremely extends the flame ofthe burner 37, and the hot air, the some and others are in contact withthe flame for a long time (a holding time of not less than 2 sec isrequested with respect to a newly constituted furnace in the secondaryguideline of Waste Management Law issued in January, 1997). Therefore,the inside of the cyclone furnace 35 can maintain a high temperature ora ceramic heat retaining material may be provided inside to maintain ahigh temperature by the thermal storage effect. (In the above-mentionedguideline, an incineration temperature of not less than 850° C., orpreferably not less than 900° C. is requested. 1100° C. or a highertemperature is designated for incineration of PCBs.)

Further, since the air supplying tube 38 for leading the fresh air intothe blower 39 is connected to the air leading tube 60 which passes thecooling tank portion 9, the air led into the blower 39 becomes anextremely cold air capable of cooling down the high temperature hot airin the cyclone furnace 35 at a blast (it is said that the rapid cooldown of the combustion gas to not above 200° C. (there is a researchresult mentioning that the cool down to not above 200° C. inapproximately 1 sec is necessary) is required in order not to recombinedioxins at approximately 300° C.).

Therefore, toxic substances such as dioxin, NOx, SOx, HCI and otherscontained in the hot air, the smoke and others can be pyrolyzed in thecyclone furnace 35 to remove the smoke, dust and others.

The air leading tube 36 and the air supplying tube 38 connected to theburner 37 and the blower 39 have one ends connected to the air intakebox 11 a to take in the fresh air. In addition, the gas flue 40 attachedto the cyclone furnace 35 of the first smoke feeding portion 4 isconnected to the smoke combustion portion 5.

Drive of the burner 37 and the blower 39 provided to the first smokefeeding portion 4 may be automatically controlled by a computer. Inaddition, sensors for detecting a combustion temperature, an exhausttemperature, a water content and others may be provided in the cyclonefurnace 35 in order to allow automatic control by a computer. In themultifunctional disposal apparatus according to the present invention,the kiln furnace 3 may not be provided. The kiln furnace 3 may beprovided in front of the dry combustion furnace 2. In themultifunctional disposal apparatus according to the present invention,the dry combustion furnace 3 itself may not be provided.

Description will now be given on the smoke combustion portion 5 and thedust filter portion 6 shown in FIG. 4. As shown in FIG. 4, the smokecombustion portion 5 again burns at a high temperature the hot air, thesmoke and the gas which are emitted from the first smoke feeding portion4 and substantially defused so that they are completely burned.

The smoke combustion portion 5 is made up of a gas flue 40, a catalyticburner 41, an auxiliary catalytic burner 42, an air leading tube 43, anair intake box 43 a, and a heating burner 43 b. The catalytic burner 41is a cylindrical body provided between the gas flues 40 and 44. In orderto accept from the auxiliary catalytic burner 42 the preliminary heatrequired for producing a high temperature at which the dioxins and thetoxic gas are burned, the auxiliary catalytic burner 42 is provided tothe catalytic burner 41.

In order to burn the fed gas at an extremely high temperature, thecatalytic burner 41 and the auxiliary catalytic burner 42 includenozzles 41 a and 42 a for spraying coal oil, crude oil or gas and thelike; mixers 41 b and 42 b for burning the mixed gas; thermal catalysts41 c and 42 c; and ceramics 41 d and 42 d. The nozzles 41 a and 42 a forspraying coal oil, crude oil or gas and the like may be stoves orheaters. Besides coal oil, crude oil or gas and the like, liquidhydrogen may be sprayed. The following is the same as above.

The fresh air is taken from the air leading tube 43 connected to the airintake box 11 a into the heating burner 43 b and the auxiliary catalyticburner 42. In the heating chamber 42 e retaining the heat generated bycombustion of the heating burner 43 b, the fresh air taken into theauxiliary catalytic burner 42 is heated, and coal oil, crude oil or gasand the like is sprayed to the heated fresh air from the nozzle 42 a toform a mixed gas of the heated fresh air and the sprayed gas.

A plurality of thermal storage mediums 42 f consisting of ceramics, heatresistant metals and others are provided inside the heating chamber 42e, heating the thermal storage mediums 42 f by the heating burner 43 bcauses the heat of the heating burner 43 b to be stored. When heating iscarried out beyond the capacity of the thermal storage mediums 42 f, aninfrared ray or heat is emitted to maintain the heating chamber 42 e ata high temperature.

A temperature of the mixed gas of the heated fresh air and the spray gasincreases to a flash point to start combustion, and the mixed gas passesthe mixer 42 b to further mixed up. The mixed gas in the combustionstate is subjected catalytic combustion by passing through the thermalcatalyst 42 c. After passing the thermal catalyst 42 c, the mixed gasbecomes a thermal catalytic high-temperature gas having a temperature ofapproximately 800° C. to 1300° C. The thermal catalytic high-temperaturegas passes through the ceramic 42 d having a honeycomb structure to besupplied to the catalytic burner 41.

In the catalytic burner 41, the gas passing the flue 40 via the firstsmoke feeding portion 4 is mixed with the thermal catalytichigh-temperature gas, and coal oil, crude oil, gas or liquid hydrogen issprayed or burned to form the mixed gas.

The temperature of the mixed gas increased to a flash point(approximately 200° C. to 250° C.) to start the combustion, and the gasis well mixed up while passing through the mixer 41 b. The mixed gas inthe combustion state is subjected to catalytic combustion atapproximately 400° C. by passing the thermal catalytic 41 c. The mixedgas then passes through the thermal catalyst to become the thermalcatalytic high-temperature gas having a temperature of approximately800° C. to 1300° C. The thermal catalytic high-temperature gas passesthrough the ceramic 41 d having a honeycomb structure to be fed to thegas flue 44.

The gas passing through the catalytic burner 41 is subjected to completecombustion as the thermal catalytic high-temperature gas, and theexhaust gas emitted to the gas flue becomes a complete combustion gascontaining a minute amount of dust. The toxic substances such asdioxins, toxic gases, NOx, SOx, HCI and others are completely decomposedand removed from the complete combustion gas.

The dust contained in the exhaust gas is filtered by the dust filterportion 6 provided between the gas flues 44 and 47. The dust filterportion 6 is divided into the gas flue allowing passing through the dustfilter apparatus 46 and the gas flue 45 which does not allow passingthrough the dust filter apparatus 46. The filter apparatus is providedin order to allow passing through the gas flue 45 by controlling theopening/closing valves 44 a and 45 a when the complete combustion gasobtained after passing through the smoke combustion portion 5 containsno dust or when the dust filter 46 is not provided or not operated. Thisdust filter device 46 may not be provided to the multifunctionaldisposal apparatus 1.

Since it is generally known that combining dioxins during cooling downthe exhaust gas tends to advance using the funnel fume in the exhaustgas as the catalyst, the combustion smoke is held at a high temperatureby the catalytic burner 41 of the smoke combustion portion 5 tocompletely oxidize and decompose the dioxins. Thereafter, the funnelfume in the exhaust gas is removed before rapid cool down in the cyclonefurnace 48 of the second smoke feeding portion 7. This is the veryeffective means.

The dust filter device 46 is constituted by a filter, a bug filter, anelectric dust collector, a wet dust collecting device, a spray tower andothers. The dust filter device 46 has a structure made up of acombination of some or all of the filter, the bug filter, the electricdust collector, the wet dust collecting device, the spray tower andothers. A combination of these members for constituting the dust filterdevice 46 can be changed to be used with taking components and the likeof an object to be incinerated such as the refused to be disposed intoconsideration.

The filter is obtained by making each of burnt lime, calcium hydroxideand activated carbon in the form of powder, particles or sponge, moldingthem into one plate to be superimposed in the form of layers. Thisfilter transmits the exhaust gas through the plate-layered burnt lime,calcium hydroxide and activated carbon to remove the funnel fume and thetoxic gas.

The bug filter has a capability for collecting fine particles by acollecting device for collecting the fine powder using a filter fabricbag and the like and is generally often used in an electric vacuumcleaner and the like. Since the temperature of the exhaust gas isextremely high, a material for the filter fabric bag must be carefullyselected. In particular, when the temperature is too high for the filterfabric, water must be sprayed, injected or dropped from a nozzle tolower the temperature of the exhaust gas.

The electric vacuum cleaner is a device for collecting the fineparticles on an electrode plate by the static charge force and oftenprovided to an exhaust flue of a plant and the like. This is a machinethat generates the corona discharge therein and impresses the funnelfume to the negative to be collected to the positive pole.

The wet dust collecting device rapidly lowers the temperature whileremoving impurities by spraying or injecting water to the exhaust gascontaining the dust and it is a so-called scrubber. It is used forscrubbing the components which are soluble in water a small amount ofwhich exists in the exhaust gas. There can be utilized a cyclonescrubber for collecting the funnel fume by causing the dust containingexhaust gas which spirally moves up in the cylinder to collide with theliquid drops sprayed from the center of the cylinder in the radialdirection or a fluidized bed scrubber which collects the funnel fume bydropping the liquid from the upper nozzle while causing the hollowsynthetic resin like a table tennis ball as a filler to be floated bythe exhaust gas flow.

The spray tower is an application of the scrubber which removes thefunnel fume by dispersing liquid drops, liquid films or bubbles of acleaning fluid from multiple nozzles in the counter direction of thedust containing exhaust gas flow and it is a so-called cooling tower. Asthe time in which the liquid drops are in contact with the exhaust gasis long, the ratio for removing the toxic gas or funnel fume becomeshigher, and this tower is often used in a small incinerator.

An opening/closing valve 47 a is provided to a gas flue 47 connected tothe dust filter device 46, and an exhaust tube 28 of the melting device10 is connected at a rear position of the opening/closing valve 47 a.When the melting device 10 is operated, the hot air used for melting theexpanded polystyrene and the polymer-based substance at a hightemperature is supplied to the gas flue 47.

When again burning only the gas which has passed the dust filter portion6 in the second smoke feeding portion 7, the opening/closing valve 28 aof the exhaust tube 28 is closed and the opening/closing valve 47 a ofthe gas flue 7 is opened. When again burning also the hot air which haspassed the melting device 10 in the second smoke feeding portion 7, boththe opening/closing valve 28 a and the opening/closing valve 47 a areopened.

All the valves 44 a, 45 a and 47 a, the heating burner 43 b, and thenozzles 41 a and 42 a provided to the smoke combustion portion 5 and thedust filter portion 6 may be automatically controlled by a computer.Various kinds of sensors for detecting a combustion temperature, anexhaust temperature, a water content and others may be provided to thegas flues 40 and 44, the catalytic burner 41, the auxiliary catalyticburner 42, the dust filter device 46 and others for allowing automaticcontrol by a computer.

As shown in FIG. 3, the gas flue 47 of the dust filter portion 6 isconnected to the cyclone furnace 48 of the second smoke feeding portion7. The second smoke feeding portion 7 is made up of the cyclone furnace48, the air leading tube 49 for taking in the air, the burner 50, theair tube 51, the blower 52, the air supplying tube 52 a and the flue 53.Since the tip of the air supplying tube 52 a attached to the blower 52is slightly inserted into the lower end 53 a of the flue 53, the airsupplied from the tip 52 b of the air supplying tube 52 a connected tothe blower 52 is blown to the lower end 53 a of the flue 53, and the airis emitted to the flue 53 while taking in the smoke, the hot air andothers in the cyclone furnace 48 by the ejector effect. Therefore, theinside of the cyclone furnace 48 constantly forms a vacuum. There may beemployed a method for inserting a pipe directly into the flue andsupplying the air by the blower to maintain the air in the furnace to bevacuum. Alternatively, an induction fan may be used.

Further, as shown in FIG. 3, the gas such as the hot air, the smoke andothers supplied from the dust filter portion 6 or the melting device 10is blown to a position slightly shifted from the center of the upperpart of the cyclone furnace 48 and gradually moves down the funnel fumecontained in the hot air or the smoke to be blown down while rotating inthe cyclone furnace 48. Here, the burner 50 attached for acceleratingthe rotational direction of the hot air or the smoke is used to againburn the gas so that the gas can be subjected to complete combustion tobe nontoxic.

A vortex flow in the cyclone furnace 48 ensures the flame of the burner50 to extremely extend, and the hot air or the smoke can come intocontact with the flame for a long period of time, thereby maintainingthe inside of the cyclone furnace 48 at a high temperature. Further,since the air tube 51 for leading the fresh air into the blower 52 isconnected to the air leading tube 60 passing the cooling tank portion 9,the air led into the blower 52 becomes a very cold air, and the hot airmaintained at a high temperature in the cyclone furnace 48 can be cooleddown at a blast.

Therefore, the toxic substances such as dioxins, NOx, SOx, HCI andothers contained in the hot air or the smoke can be completely pyrolyzedin the cyclone furnace 48, and the smoke, the dust and others can becompletely removed at last.

The air leading tube 49 and the air tube 51 connected to the burner 50and the blower 52 have one ends communicating with the air intake box 11a so that the fresh air can be taken in. Moreover, the flue 40 piercesfrom the cyclone furnace 48 to the outside of the multifunctionaldisposal apparatus 1 and discharges the nontoxic defused gas to theoutside of the apparatus 1.

Driving of the burner 50 and the blower 52 provided to the second smokefeeding portion 7 may be automatically controlled by a computer. Sensorsfor detecting a combustion temperature, an exhaust temperature, a watercontent, a vacuum state, a smoke and others may be provided in thecyclone furnace 48 to allow automatic control by a computer.

A plurality of thermal storage mediums 57 a of ceramics, heat resistantmetals, or others are provided in the heating chamber 57. When the heatstorage mediums 57 a are heated by the heating burner 55, the heat ofthe heating burner 55 is stored. Also, when heating is carried outbeyond the capacity of the thermal storage mediums 57 a, an infrared rayor heat is emitted, thereby maintaining the heating chamber 57 at a hightemperature.

The air supplying tube 58 is connected to an air cooling tube 61 of thecooling tank portion 9, the air supplying tube 22 of the dry combustionfurnace 2, and the air supplying tube 25 of the melting device 10.

When supplying the hot air to the air supplying tube 22 of the drycombustion furnace 2, the cold air or the gas which is a mixture of thehot air and the cold air having a medium temperature may be supplied aswell as the hot air. Therefore, the temperature of the gas supplied tothe air supplying tube 22 can be adjusted by controlling a valve travelof the opening/closing valve 61 b of the air cooling tube 61.

Of course, adjustment of a heating quantity of the heating burner 55 ofthe air heating portion 8 or valve travels of the opening/closing valve58 a of the air supplying tube 58, the opening/closing valve 22 a of theair supplying tube 22, the opening/closing valve 61 b of the air coolingtube 61 may be automatically controlled by a computer. Sensors fordetecting a combustion temperature, a temperature, a water content, avacuum state, a smoke and others may be provided in the heating chamber57, the air supplying tube 22 and others to allow automatic control by acomputer.

The cooling tank portion 9 is made up of a water tank 59, an air leadingtube 60, an air cooling tube 61, an endothermic tube 62, a circulationtube 30, a freezing machine 63, and a circulation tube 64.

The air cooling tube 61 is used for leading the fresh air to the drycombustion furnace 2. This tube 61 is provided in order to lower thetemperature of the hot air heated by the air heating portion 8 to be ledinto the dry combustion furnace 2 or absorb the dry cold air into thedry combustion furnace 2. To the air cooling tube 61 are provided thecooling portion 61 a which is disposed in the corrugated form at aportion communicating with the water tank and the opening/closing valve61 b so that the fresh cold air led into the dry combustion furnace 2can be supplied while adjusting an amount thereof. Since the cold aircan be absorbed by forming a vacuum in the furnace, uniform supply ofthe air in the furnace can be utilized.

In order to cool down the water or the liquid reserved in the water tank59, the endothermic tube 62 provided to the cooling machine 63 isdisposed in the water tank 59. A coolant having a low coagulation pointwhich is cooled down in the freezing machine 63 is circulated in theendothermic tube 62, and this coolant takes heat from the water or theliquid in the water tank through the endothermic tube 62 to cool downthe water or the liquid.

The circulation tube 30 connected to the combustion chamber 17 of thedry combustion furnace 2 is connected to the freezing machine 63 totransmit the combustion heat obtained from the combustion chamber 17 tothe freezing machine 63 by using the hot water, steam and others in thecirculation tube 30. The combustion heat is used in the freezing machine63 to cool down the coolant.

The circulation tube 30 led to the freezing machine 63 is connected tothe freezing machine or a turbine generator to generate the electricityby utilizing the hot water or the steam circulating in the circulationtube 30. Further, this tube 30 may be used for driving the burner, theblower, the kiln furnace, the dry plates, the grating plate, thefreezing machine used in the multifunctional disposal apparatus 1,opening/closing the valve, or as a power supply of a belt conveyer forinputting the refuse or an air cooler provided in facilities. Inaddition, the night power and the incineration heat are used, and thefreezing machine is also used. The ice storage is used for an air coolerin facilities.

Of course, the generator is not restricted to the turbine generator, andit may be used together with an aerogenerator, a photovoltaic generator,a liquid hydrogen generator, a fossil fuel of a solar battery, anaccumulator battery and others instead of the turbine generator.Moreover, a generation method using no atomic energy may be adopted.

A circulation tube 64 for circulating the cooling water for an aircooler in a facility or a room by using the thermal heat of the watertank 59 is inserted into the water tank 59 of the cooling tank portion9.

A degree of opening/closing of the opening/closing valve 59 b of thewater tank 59 and the opening/closing valve 61 b of the cooling tube 61of the cooling tank portion 9 and driving of the freezing machine 63 maybe automatically controlled by a computer.

FIG. 6 is an overall cross-sectional view showing an embodiment of amultifunctional disposal apparatus according to the present invention.In this embodiment, heat radiators 68 connected to a heat pipe 67 aresubstituted for the heating burners 20 a, 43 b and 55 provided to thedry combustion furnace 2, the smoke combustion portion 5 and the airheating portion 8 of the multifunctional disposal apparatus 1illustrated in FIG. 1.

The heat pipe 67 transmits the heat of the solar energy collected by aparabola condenser 66 set outside the multifunctional disposal apparatus1 a to the heat radiators 68 provided to the heating chambers 20, 42 eand 57 of the dry combustion furnace 2, the smoke combustion portion 5and the air heating portion 8.

One end of the heat pipe 67 is connected to the parabola condenser 66,and branching heat pipes 67 a, 67 b and 67 c are provided. Further, theother ends of the heat pipes 67 a, 67 b and 67 c are connected to theheat radiators 68 to transmit the heat of the condenser 66. As to amaterial of the heat pipes 67 a, 67 b and 67 c, pipes using a heattransfer metal as its material or pipes using ceramics as its materialmay be used.

The structure for transmitting the heat of the solar energy to therespective heat radiators 68 may be adopted by using the parabolacondenser 66 as a lens condenser. Alternatively, a method for convertingthe energy into the electricity to transmit the heat of the heater maybe used.

In the multifunctional disposal apparatus la illustrated in FIG. 6,although the first smoke feeding portion 4 and the dust filter portion 6provided to the multifunctional disposal apparatus 1 illustrated in FIG.1 are not shown, the first smoke feeding portion 4 and the dust filterportion 6 may or may not be provided.

In the dry combustion furnace 2 of the multifunctional disposalapparatus 1 a, although the ash access door 18 a is provided in order totake out the incinerated ash accumulated on the ash pan 17 c to theoutside of the dry combustion furnace 2, rails d may be provided insideor outside the ash access door 18 a and wheels and the like may beattached to the ash pan 17 c for enabling sliding in order to facilitateaccess to the ash pan 17 c. In addition, a screw conveyer or a beltconveyer may be attached instead of the rails 17 d.

In the dry combustion furnace 2 of the multifunctional processingapparatus 1 a, the funnel fume access door 24 is provided in order totake out the funnel fume accumulated on the funnel fume pan 23 tooutside of the dry combustion furnace 2, but rails 23 a are providedinside or outside the funnel fume access door 24 and wheels and the likeare also attached to the funnel fume pan 23 for enabling sliding inorder to facilitate access to the funnel fume pan 23. Further, a screwconveyer or a belt conveyer may be attached instead of the rails 23 a. Avibrating belt conveyer may be also used.

In addition, there is provided a screw conveyer 65 in order that the ashaccess door 18 a is opened to take out the ash pan 17 c and theincinerated ash accumulated on the ash pan 17 c is moved to the kilnfurnace 3. A belt conveyer or a vibrating belt conveyer and the like maybe employed as the screw conveyer 65.

Of course, driving of the opening/closing valve, the burner, the blower,the conveyer, the parabola condenser and the like provided to themultifunctional disposal apparatus 1 a shown in FIG. 6 may beautomatically controlled by a computer. Sensors for detecting atemperature, a humidity, a water level, a vacuum state and others may beprovided for enabling automatic control by a computer.

FIG. 7 is a partially enlarged view of another embodiment of themultifunctional disposal apparatus according to the present invention.In this embodiment, the first smoke feeding portion 4 provided at therear of the kiln furnace 3 of the multifunctional disposal apparatus 1and 1 a is provided as an ash melting portion 71 and a smoke feedingportion 77. The structure in which the ash melting portion 71 and thesmoke feeding portion 77 are provided at the rear of the dry combustionfurnace 2 may be also adopted.

A gas flue 70 extending from the center of one end 31 b of the kilnfurnace 3 is provided to the kiln furnace 3, and the ash melting portion71, the gas flue 75 and the smoke feeding portion 77 are continuouslyprovided to the other end of the gas flue 70.

The ash melting portion 71 is constituted by a melting furnace 72 havinga cover 72 a, a heating burner 73, a crucible 74 having a cover 74 a,and a fire brick 74 b. The cover 72 a is attached to the top face of themelting furnace 72 having a castable refractory and the like on theinner wall surface thereof so that the cover can be opened/closed, andthe heating burner 73 diagonally facing upwards is provided on the sidesurface of the same.

The fire bricks 74 b are heaped up on the inner bottom of the meltingfurnace 72 or the castable refractory is used to build a base, and thecrucible 74 is mounted and formed thereon. The crucible 74 has acylindrical shape, and a plurality of leg portions are extendeddownwards from the bottom face while the top face is opened. The cover74 a having a hole is put on the top face, and the incinerated ashobtained from the dry combustion furnace 2 or the kiln furnace 3 isfilled in the crucible 74.

The hot air containing the smoke supplied from the kiln furnace 3 or thedry combustion furnace 2 is used to completely burn a small amount ofremaining unburned gas, funnel fumes, toxic gases such as COx, SOx, NOxand others, dioxins at a high temperature of approximately 1300° C.1800° C. by the relatively large heating burner 73 provided to the ashmelting furnace 71. The crucible 74 can be heated by the high heatobtained by heating of the heating burner 73 and the incinerated ashaccommodated in the crucible 74 can be molten.

The flame surrounding the crucible 74 has a spiral form around thecrucible 74 due to the hot air from the kiln furnace 3 or the drycombustion furnace 2, the power of the mixed gas combustion andprovision of the heating burner 73 at a orthogonal lower position,thereby uniformly heating the entire crucible 74.

When the fire bricks 74 b are provided around the crucible 74, theinside of the ash melting furnace 72 can be maintained at a hightemperature by heat storage and heat retention effect. If a gap isprovided around the crucible 74 to fill the fire bricks 74 b or thecastable refractory and the like therein, the inside of the crucible 74can be further stabilized at a high temperature.

The incinerated ash obtained by incinerating paper or wood, raw refuses,resin and others which can be included in the regular incinerated ashcan be used for complete carbonization by combustion as well asevaporation of components of carbon, oxygen, nitrogen and others at anextremely high temperature. However, a small amount of incombustiblematerials such as metals, heavy metals, glass and others is generallymixed in any other components of the combustible object to beincinerated.

The heavy metal is contained in the incinerated ash, and it canadversely affect animate and human beings or a natural world when theincinerated ash is landfilled as it is. Therefore, the incinerated ashcan be molten in the ash melting furnace 72 and cooled down to be hardenfor disposal. Thereafter, the cover 72 a is opened to take out the cover74 a, and the agglomerate in the crucible 74 is taken out and cooleddown to be hardened.

The agglomerate obtained by melting and hardening the ash is atranslucent agglomerate like a marble containing the heavy metals andothers. The thus obtained molten object of the incinerated ash can bedisposed by being mixed in cement as similar to gravels forming anaggregate for a building material or concrete.

A filter 76 is provided in the gas flue 75 connecting the ash meltingportion 71 to the smoke feeding portion 77. The dustcollecting/filtering effect of the filter 76 is increased by utilizing athermal catalytic filter, a ceramic filter and others. Clogging of thefilter can be suppressed since complete incineration is carried out byusing the combustion heat in the front stage. The clogs can be burnedwhen a burner and the like is attached. Any kind of the filter 76 can beused if it permeates the air, the vapor and others therethrough. Poresof 50 angstrom to 500 angstrom are produced to the filter, and theinside of the dry combustion chamber 2 and that of the kiln furnace 3form a vacuum when molecules of the air pass the pores. When the filter76 is used as a ceramic filter and pores of 50 angstrom to 500 angstromare formed, molecules of the smoke and the like do not pass through thepores. It is to be noted that since a number of molecules of the air isseveral angstrom to 50 angstrom, the ceramic filter may not be used.

The smoke feeding portion 77 is constituted by a cyclone furnace 78having a cover 78 a, a burner 79, a blower 80, an air supplying tube 80a and a gas flue 81.

Since a tip of the air supplying tube 80 a attached to the blower 80 isslightly inserted into a tube end 81 a of the gas flue 81, the airsupplied from a tip 80 b of the air supplying tube 80 a connected to theblower 80 is blown to the lower end 81 a of the gas flue 81. The air isfurther exhausted to the gas flue 81 while taking in the smoke, the hotair and the like in the cyclone furnace 78 by the ejector effect, andthe inside of the cyclone furnace 78 constantly forms a vacuum.

The hot air, the smoke and others blown from the ash melting portion 71are blown from the upper portion of the cyclone furnace 78 and graduallymove down the funnel fume contained in the hot air or the smoke whilerotating in the cyclone furnace 78. Here, when the burner 79 attachedfor accelerating the rotational direction of the hot air or the smoke isused to again burn the hot air, the smoke and others, they arecompletely burned to be nontoxic.

A vortex flow in the cyclone furnace 78 causes the flame of the burner79 to extend extremely long, and the hot air or the smoke comes intocontact with the flame for a long period of time, thereby maintainingthe inside of the cyclone furnace 78 at a high temperature.

A crucible 82 for melting and hardening the ash is provided on the outerperipheral surface of the gas flue 81 formed in the center of thecyclone furnace 78. As shown in FIG. 7, the crucible 82 is constitutedby a double cylinder and has a structure in which a bottom is formedbetween the outer cylinder and the inner cylinder. Further, a cover 82 ahaving a hole is put on the top face. In this manner, results ofmelting, heat radiation, heat storage can be simultaneously obtained.

The flame of the burner spirally formed keeps the crucible 82 at a hightemperature and melts the ash accommodated in the crucible 82. Afteropening the cover 78 a for the crucible 82 and removing the cover 82 a,the molten object which is cooled down and hardened after taken out fromthe crucible is taken out.

The air supplied from the air supplying tube 80 a from the blower 80 cancool down the hot air in the cyclone furnace 78 at a high temperature ata blast and supply the air in the cyclone furnace 78 to the gas flue 81.Therefore, toxic substances such as dioxins, NOx, SOx, HCI and otherscontained in the hot air or the smoke can be pyrolyzed in the cyclonefurnace 35 to remove the smoke, the dust and others.

Driving of the burner 79, the blower 80 provided to the smoke feedingportion 77 may be automatically controlled by a computer. Sensors fordetecting a combustion temperature, an exhaust temperature, a watercontent, a vacuum state and others may be provided in the cyclonefurnace 78 in order to enable automatic control.

With reference to FIGS. 8 to 16, a method for disposing an object to bedisposed by using the multifunctional disposal apparatuses 1 and 1 aaccording to the present invention will now be described in detail. Thatis, description will be given as to the method for disposing the rawrefuse, the sludge, the general garbage, the expanded polystyrene, thepolymer-based substance and others by utilizing the multifunctionaldisposal apparatus 1 shown in FIGS. 1 to 5, the multifunctional disposalapparatus 1 a shown in FIG. 6, the ash melting portion and the smokefeeding portion shown in FIG. 7 and the processing steps thereof. FIG. 8shows a disposal method by microbial degradation; FIG. 9, a disposalmethod by pyrolysis; FIG. 10, a disposal method by low-temperaturedrying; FIG. 11, a disposal method by indirect hot air drying; FIG. 12,a disposal method by direct hot air drying; FIG. 13, a disposal methodby carbonization; FIG. 14, a disposal method by incineration; FIG. 15, adisposal method by melting expanded polystyrene and polymer-basedsubstance; and FIG. 16, a method for melting the incinerated ash byusing the multifunctional disposal apparatus.

Here, there are two methods of indirect hot air drying.

FIG. 8 is a flowchart showing a disposal method by applying microbialdegradation to the raw refuse or the sludge by using the multifunctionaldisposal apparatus. The disposal method of this example maintains theraw refuse, the sludge and the like at an appropriate temperature to befermented or decomposed by using microbes or funguses.

“Raw Refuse/Sludge Input Process 101”

The raw refuse or the sludge is inputted into the first dry chamber 15from the input opening 13 a of the raw refuse/sludge input portion 13provided to the dry combustion furnace 2 of the multifunctional disposalapparatus 1 or 1 a shown in FIG. 2 or FIG. 6. The dry plate 15 a, andthe respective grating plates 15 c, 15 e and 15 g are swiveled so thatthe raw refuse or the sludge can be evenly accommodated in therespective dry chambers 15, 15 b, 15 d and 15 f.

When the sludge to be inputted is an active sludge which can be obtainedby decomposition process by the active sludge method, the microbialdegradation further advances. Of course, the raw refuse or the sludgemay be inputted from the doors 16 and 16 a of the dry combustion furnace2 into the respective dry chambers 15, 15 d and 15 f, or the raw refuseor the sludge may be inputted from the input opening of the generalgarbage input portion 14 or the door 18 into the combustion chamber 17.That is because no combustion incineration disposal is not carried outin the combustion chamber 17 in this disposal method.

The raw refuse or the sludge may be inputted from the input opening 32 aof the refuse input portion 32 provided in the kiln furnace 3 shown inFIG. 3, FIG. 6 or FIG. 7 into the kiln furnace 3. That is because thedry incineration disposal is not carried out in the kiln furnace 3 inthis disposal method.

“Heating Process 102”

The heating burner 20 a provided to the lower portion of the dryincinerator 2 shown in FIGS. 2 and 3 is ignited, or the heat radiator 68shown in FIG. 6 is driven. At the same time, the opening/closing valve58 a of the air supplying tube 58 of the air heating portion 8 shown inFIG. 3, 5 or 6 is closed, and the opening/closing valve 61 b of the aircooling tube 61 of the cooling tank portion 9 and the opening/closingvalve 22 a of the air supplying tube 22 of the dry combustion furnace 2are opened.

The fresh air is taken from the air cooling tube 61 to be led from theair supplying tube 22 to the dry combustion furnace 2. The cooling tankportion 9 may or may not be operated. The fresh air taken in the drycombustion furnace 2 is heated by the heat of the heating burner 20 aradiated from the heat radiation tube 20 b. The hot air which passes inthe heat radiation tube 20 b and is obtained by the heating burner 20 apasses through the exhaust tube 21 to be exhausted to the air intake box11 a after heat radiation.

“Suction Step 103”

The blower 39 of the first smoke feeding portion 4 or the blower 52 ofthe second smoke feeding portion 7 shown in FIG. 3, 5 or 6 is driven, orthe blower 80 of the smoke feeding portion 77 shown in FIG. 7 is drivenso that the inside of the dry combustion furnace 2 and that of the kilnfurnace 3 form a low vacuum state. Any one or some of the respectiveblowers 39, 52 and 80 may be driven or all of them may be driven. Whendriving the blowers 39, 52 and 80, control is executed in such a mannerthat the inside of the furnaces 2 and 3 entirely forms a low vacuumstate.

By forming a low vacuum state in the dry combustion furnace 2, the freshair led to the dry combustion furnace 2 to be heated slowly passes therespective dry chambers 15, 15 b, 15 d and 15 f, and the combustionchamber 17 while repeating the circulation. Further, this fresh airheats the raw refuse or the sludge accommodated in the same chambers 15,15 b, 15 d, 15 f and 17. The hot air having passed the dry combustionfurnace 2 is led into the kiln furnace 3 via the smoke leading tube 29to heat the raw refuse or the sludge accommodated in the kiln furnace 3.Fermentation is carried out by rotating the cylindrical body 31 by thekiln furnace 3.

“Heat-retaining Fermentative Degradation Step 104”

The raw refuse and the sludge accommodated in the respective drychambers 15, 15 b, 15 d and 15 f and the combustion chamber 17 are keptwarm at a temperature suitable for microbes or fungus existing in theraw refuse or the sludge to be activated by appropriately continuouslydriving the heating burner 20 a of the dry combustion furnace 2 and alsoappropriately continuously driving the blowers 39, 52 and 80. Themicrobes or fungus are bred to ferment or degrade the raw refuse or thesludge. Of course the microbes or fungus for advancingfermentation/degradation can be put in the respective dry chambers 15,15 b, 15 d and 15 and the combustion chamber 17. When the vacuum stateis formed to absorb the air for ventilation, the air can be evenly takenin with respect to the raw refuse, the sludge and others which are theobject to be incinerated, thereby accelerating thefermentation/degradation.

“Deodorization Step 105”

The fermentation odor and the degradation odor are subjected to thecombustion process by driving the burner 37 of the first smoke feedingportion 4 and the burner 50 of the second smoke feeding portion 7 or thesmoke combustion portion 5 shown in FIG. 3, 4, 5 or 6 or driving theburner 79 of the smoke feeding portion 77 shown in FIG. 7. Thedeodorized gas is exhausted from the flue 53 of the second smoke feedingportion 7 to the outside of the multifunctional disposal apparatus 1 or1 a. Here, the dust filter device 46 of the dust filter portion 6 is notused. The opening/closing valve 44 a of the gas flue 44 is closed andthe opening/closing valve 45 a of the gas flue 45 is opened so that thegas to be exhausted is bypassed from the smoke combustion portion 5 tothe second smoke feeding portion 7.

“Disposal Object Fetch Step 106”

The object to be disposed such as the raw refuse or the sludgeaccommodated in the dry combustion furnace 2 can be taken out from thedoors 16, 16 a and 18 upon completion of fermentation/degradation usingthe microbes or bacteria. The object to be disposed such as the rawrefuse or the sludge accommodated in the kiln furnace 3 can be rakedinto the storage chamber 33 to be accommodated or fetched.

The object of disposal taken out from the doors 16, 16 a and 18 or thestorage chamber 33 can be processed in any other processing step, andthe disposal object obtained from the raw refuse or the sludge can be ofcourse used as fertilizers for a plow land or a fruit farm, a kitchengarden, a wadi and others or feeding stuffs for domestic animals such asa pig. Further, it can be accommodated in the dry combustion furnace 2and incinerated as a burnable garbage later.

FIG. 9 is a flowchart showing a method for pyrolyzing the generalgarbage or the incinerated ash by using the multifunctional disposalapparatus according to the present invention. The disposal method inthis example pyrolyzes harmful substances such as harmful gases, e.g.,NOx, COx, SOx and dioxins contained in the general garbage or theincinerated ash and the like including the raw refuse or the sludge atan extremely high temperature to be nontoxic.

“Refuse Input Process 111”

The raw refuse or the sludge is inputted from the raw refuse/sludgeinput portion 13 provided to the dry combustion furnace 2 of themultifunctional disposal apparatus 1 or 1 a shown in FIG. 2 or FIG. 6into the first dry chamber 15, and the general garbage or theincinerated ash is inputted from the input opening 14 a of the generalgarbage input portion 14.

The incinerated ash can be inputted from the doors 16, 16 a and 18 intothe respective dry chambers 15, 15 d and 15 f or the combustion chamber17, or the incinerated ash remaining in the ash pan 17 c may be left asit is because it can be degraded. Moreover, the raw refuse or the sludgecan be evenly accommodated in the respective dry chambers 15, 15 b, 15 dand 15 f by swiveling the dry plate 15 a and the respective gratingplates 15 c, 15 e and 15 g.

“Heating Process 112”

The heating burner 20 a provided to the lower portion of the dryincinerator 2 shown in FIGS. 2 and 3 is ignited, or the heat radiator 68shown in FIG. 6 is driven. At the same time, the opening/closing valve58 a of the air supplying tube 58 of the air heating portion 8 shown inFIG. 3, FIG. 5 or FIG. 6 is closed, and the opening/closing valve 61 bof the air cooling tube 61 of the cooling tank portion 9 and theopening/closing valve 22 a of the air supplying tube 22 of the drycombustion furnace 2 are opened.

The fresh air is taken from the air cooling tube 61 to be led from theair supplying tube 22 into the dry combustion furnace 2. The coolingtank portion 9 may or may not be operated. The fresh air taken into thedry combustion furnace 2 is heated by heat of the heating burner 20 aradiated from the heat radiation tube 20 b. The hot air obtained by theheating burner 20 a passing through the heat radiation tube 20 b isradiated and then passes through the exhaust tube 21 to be emitted intothe air intake box 11 a.

“Suction Step 113”

The blower 39 of the first smoke feeding portion 4 or the blower 52 ofthe second smoke feeding portion 7 shown in FIG. 3, 5 or 6 are driven,or the blower 80 of the smoke feeding portion 77 shown in FIG. 7 isdriven so that the inside of the dry combustion furnace 2 and that ofthe kiln furnace 3 form a vacuum. Any one or some of the respectiveblowers 39, 52 and 80 may be driven or all of them may be driven.

When the inside of the dry combustion furnace 2 forms a vacuum, thefresh air led into the dry combustion furnace 2 to be heated passesthrough the respective dry chambers 15, 15 b, 15 d and 15 f and thecombustion chamber 17 and heats the raw refuse or the sludgeaccommodated in the respective dry chambers 15, 15 b, 15 d and 15 f andthe general garbage or the incinerated ash accommodated in thecombustion chamber 17. At this time, the dust filter device 46 of thedust filter portion 6 is not used. The opening/closing valve 44 a of thegas flue 44 is closed and the opening/closing valve 45 a of the gas flue45 is opened so that the gas to be exhausted from the smoke combustionportion 5 is bypassed to the second smoke feeding portion 7.

“Sealing Process 114”

When the dry combustion furnace 2 is uniformly warmed (approximately300° C. to 500° C.), driving the respective blowers 39, 52 and 80 isstopped. Also, the opening/closing valve 29 a of the smoke leading tube29 and the opening/closing valve 22 a of the air supplying tube 22 shownin FIG. 2, 3, 5 or 6 are closed so that the inside of the dry combustionfurnace 2, i.e., the respective dry chambers 15, 15 b, 15 d and 15 f andthe combustion chamber 17 are completely sealed.

“Pyrolysis Process 115”

When completely sealed, the inside of the dry combustion furnace 2contains a large amount of unburned gas and unburned carbon generated ata high temperature and lacks oxygen to be in the reduced atmosphere.Under the reduced atmosphere, the harmful substances such as carbonmonoxide and dioxins can be prevented from being generated, and thedensity of oxygen is extremely thin under the reduced atmosphere. Whenfurther applying heating and pyrolyzing at a temperature of not lessthan 450° C., the dioxins become nontoxic, and a nitrogen oxide, asulfur oxide and a hydrogen chloride are pyrolyzed, thereby reducing anamount of the harmful substances such as dioxins, NOx, SOx, HCL andothers contained in the gas generated due to pyrolysis.

“Disposal Object Fetch Process 116”

The disposal object such as a general garbage or an incinerated ashcontaining a raw refuse and a sludge accommodated in the dry combustionfurnace 2 can be taken out from the doors 16, 16 a and 18 upon pyrolysisunder the reduced atmosphere.

The disposal object taken out from the doors 16, 16 a and 18 can beprocessed in any other processing step, and the disposal object obtainedfrom the raw garbage or the sludge can be of course used as fertilizersfor a plow land or a fruit farm, a kitchen garden, a wadi and others orfeeding stuffs for domestic animals such as a pig. Further, it can beaccommodated in the dry combustion furnace 2 and incinerated as aburnable garbage later.

FIG. 10 is a flowchart showing the method for applying thelow-temperature drying process to the raw refuse or the sludge by usingthe multifunctional disposal apparatus according to the presentinvention shown in FIG. 10. The disposal method of this example driesthe raw refuse or the sludge at a low temperature without generating theodor.

“Cooling Tank Portion Operating Step 121”

Water, rain water or others is first inputted into the water tank 59 ofthe cooling tank portion 9 shown in FIG. 5 from the input opening 59 aprovided to the water tank 59, and water is reserved while regulatingthe input by using the opening/closing valve 59 b. In a heavy snowfallarea, snow, ice and others may be reserved and the reserved snow, iceand others may be inputted from the input opening 59 a.

By utilizing the night power or utilizing power obtained from wind powergeneration, turbine power generation, solar power generation and others,the freezing machine 63 is driven to produce a frost ice 62 a in thewater tank 59 by the endothermic tube 62. Cooling down the inside of thewater tank 59 causes the fresh air passing through the air leading tube60 and the air cooling tube 61 to be cooled and dried. In particular,the fresh dried cold air passing through the air cooling tube 61 is ledinto the dry combustion furnace 2 via the air supplying tube 22. Whenthe freezing machine is driven by using the night power to utilize theice thermal storage, the cold blast can be used in the daytime.

“Refuse Input Step 122”

The raw refuse or the sludge is inputted into the first dry chamber 15from the input opening 13 a of the raw refuse/sludge input portion 13provided to the dry combustion furnace 2 of the multifunctional disposalapparatus 1 or 1 a shown in FIG. 2 or 6. The dry plate 15 a and therespective grating plates 15 c, 15 e and 15 g are swiveled or rotated sothat the raw refuse or the sludge can be evenly accommodated in therespective dry chambers 15, 15 b, 15 d and 15 f.

The raw refuse or the sludge may be inputted from the doors 16 and 16 aof the dry combustion furnace 2 into the respective dry chambers 15, 15d and 15 f, or the raw refuse or the sludge may be inputted from theinput opening 14 a of the general garbage input portion 14 or the door18 of the combustion chamber 17. That is because, the combustionincineration disposal is not performed in the combustion chamber 17 inthis processing method.

The raw refuse or the sludge may be inputted into the kiln furnace 3from the input opening 32 a of the refuse input portion 32 provided tothe kiln furnace 3 shown in FIG. 3, 6 or 7. That is because the drycombustion disposal is not performed in the kiln furnace 3 in thisprocessing method.

“Ventilation Step 123”

The opening/closing valve 58 a of the air supplying tube 58 of the airheating portion 8 shown in FIG. 3, 5 or 6 is closed, and theopening/closing valve 61 b of the air cooling tube 61 of the coolingtank portion 9 and the opening/closing valve 22 a of the air supplyingtube 22 of the dry combustion furnace 2 are opened. The fresh dried coldair passing through the air cooling tube 61 is led into the drycombustion furnace 2 via the air supplying tube 22. When leading the airinto the dry combustion furnace 2, the fresh dried cold air passingthrough the air supplying tube 22 is cooled down to be approximately notmore than 5° C. in the cooling tank portion 9 and absorbed into thefurnace.

“Suction Drying Step 124”

The blower 39 of the first smoke feeding portion 4 or the blower 52 ofthe second smoke feeding portion 7 shown in FIG. 3, 5 or 6 is driven orthe blower 80 of the smoke feeding portion 77 shown in FIG. 7 is drivenso that the inside of the dry combustion furnace 2 or that of the kilnfurnace 3 form a vacuum. Any one or some of the respective blowers 39,52 and 80 may be driven or all of them may be driven.

When the inside of the dry combustion furnace 2 forms a vacuum, thefresh dried cold air led into the dry combustion furnace 2 slowly passesthrough the respective dry chambers 15, 15 b, 15 d and 15 f and thecombustion chamber 17 while repeating the circulation and dries andcools down the raw refuse or the sludge accommodated in the chambers 15,15 b, 15 d, 15 f and 17. The dried cold air having passed through thedry combustion furnace 2 is led into the kiln furnace 3 via the smokeleading tube 29 and dries and cools down the raw refuse or the sludgeaccommodated in the kiln furnace 3. The kiln furnace 3 rotates thecylindrical body 31 to advance drying.

“Deodorization Step 125”

The burner 37 of the first smoke feeding portion 4, the burner 50 of thesecond smoke feeding portion 7 or the smoke combustion portion 5 shownin FIG. 3, 4, 5 or 6 is driven, or the burner 79 of the smoke feedingportion 77 shown in FIG. 7 is driven so that the odor obtained from theinside the dry combustion furnace 2 and that of the kiln furnace 3 issubjected to combustion process. The deodorized gas is exhausted fromthe flue 53 of the second smoke feeding portion 7 to the outside of themultifunctional disposal apparatus 1 or 1 a. Here, the dust filterdevice 46 of the dust filter portion 6 is not used. The opening/closingvalve 44 a of the gas flue 44 is closed and the opening/closing valve 45a of the gas flue 45 is opened so that the gas to be exhausted isbypassed from the smoke combustion portion 5 to the second smoke feedingportion 7.

In the low-temperature drying processing method in this example, sincethe odor is hardly generated at all, the burner 37 of the first smokefeeding portion 4, the burner 50 of the second smoke feeding portion 7,the smoke combustion portion 5 and the burner 79 of the smoke feedingportion 77 may not driven and the deodorization step 125 may be omitted.

“Disposal Object Fetch Step 126”

The object to be disposed such as the raw refuse or the sludgeaccommodated in the dry combustion furnace 2 can be taken out from thedoors 16, 16 a and 18 upon completion of the drying process using thecold air. The object to be disposed such as the raw refuse or the sludgeaccommodated in the kiln furnace 3 can be raked into the storage chamber33 to be accommodated or fetched.

The disposal object taken out from the doors 16, 16 a and 18 or thestorage chamber 33 may be processed in any other process step, and thedisposal object obtained from the raw refuse or the sludge can be ofcourse used as fertilizers for a plow land or a fruit farm, a kitchengarden, a wadi and others or feeding stuffs for domestic animals such asa pig. Further, it can be accommodated in the dry combustion furnace 2and incinerated as a burnable garbage later.

FIG. 11 is a flowchart showing the method for drying the generalgarbage, the raw refuse or the sludge with the heated hot air by usingthe multifunctional disposal apparatus according to the presentinvention. The disposal method by indirect hot air drying in thisexample dries the general garbage, the raw refuse or the sludge at amedium temperature (approximately 40° C. to 400° C.) without generatingthe odor.

“Refuse Input Process 131”

The raw refuse or the sludge is inputted into the first dry chamber 15from the input opening 13 a of the raw refuse/sludge input portion 13provided to the dry combustion furnace 2 of the multifunctional disposalapparatus 1 or 1 a shown in FIG. 2 or 6, and the general garbage isinputted from the input opening 14 a of the general garbage inputportion 14. The dry plate 15 a and the respective grating plates 15 c,15 e and 15 g are swiveled so that the raw refuse or the sludge can beevenly accommodated in the respective dry chambers 15, 15 b, 15 d and 15f.

The raw refuse or the sludge may be inputted from the doors 16 and 16 aof the dry combustion furnace 2 into the respective dry chambers 15, 15d and 15 f, or the raw refuse or the sludge may be inputted from theinput opening 14 a of the general garbage input portion 14 or the door18 into the combustion chamber 17. That is because the combustionincineration disposal is not carried out in the combustion chamber 17 inthis processing method.

In addition, the raw refuse or the sludge may be inputted into the kilnfurnace 3 from the input opening 32 a of the refuse input portion 32provided to the kiln furnace 3 shown in FIG. 3, 6 or 7. That is becausethe dry combustion disposal is not performed in the kiln furnace 3 inthis processing method.

“Heating Step 132”

The heating burner 20 a provided on the lower portion of the dryincinerator 2 shown in FIGS. 2 and 3 is ignited, or the heat radiator 68of the dry combustion furnace 2 shown in FIG. 6 is driven. At the sametime, the opening/closing valve 58 a of the air supplying tube 58 isopened, and the opening/closing valve 61 b of the air cooling tube 61 ofthe cooling tank portion 9 and the opening/closing valve 22 a of the airsupplying tube 22 of the dry combustion furnace 2 are opened. Theheating burner 55 of the air heating portion 8 is not driven.

The fresh dry cold air is taken from the air cooling tube 61 and the airsupplying tube 58 to be led from the air supplying tube 22 to the drycombustion furnace 2. The cooling tank portion 9 is driven and the airin the air cooling tube 61 is cooled down and dried as far as possible.The fresh dried cold air taken into the dry combustion furnace 2 isheated by heat of the heating burner 20 a radiated from the heatradiation tube 20 b to approximately 70° C. to 400° C. The hot airobtained by the heating burner 20 a passing through the heat radiationtube 20 b is heat-radiated and then exhausted to the air intake box 11 avia the exhaust tube 21. Further, the heat radiation tube may be formedinto a frying-pan-like shape.

“Suction Drying Step 133”

The blower 39 of the first smoke feeding portion 4 or the blower 52 ofthe second smoke feeding portion 7 shown in FIG. 3, 5 or 6 is driven, orthe blower 80 of the smoke feeding portion 77 shown in FIG. 7 is drivenso that the inside of the dry combustion furnace 2 and that of the kilnfurnace 3 form a vacuum. Any one or some of the respective blowers 39,52 and 80 may be driven or all of them may be driven.

When the inside of the dry combustion furnace 2 forms a vacuum, thefresh dried cold air led into the dry combustion furnace 2 slowly passesthrough the respective dry chambers 15, 15 b, 15 d and 15 f and thecombustion chamber 17 while repeating the circulation and dried andcools down the general garbage, the raw refuse or the sludgeaccommodated in these chambers 15, 15 b, 15 d, 15 f and 17. The driedcold air having passed through the dry combustion furnace 2 is led intothe kiln furnace 3 via the smoke leading tube 29 to dry and cool downthe raw refuse or the sludge accommodated in the kiln furnace 3. Thekiln furnace 3 rotates the cylindrical body 31 to perform drying.

“Deodorization Step 134”

The burner 37 of the first smoke feeding portion 4, the burner 50 of thesecond smoke feeding portion 7 or the smoke combustion portion 5 shownin FIG. 3, 4, 5 or 6 is driven, or the burner 79 of the smoke feedingportion 77 shown in FIG. 7 is driven so that the odor obtained from theinside of the dry combustion furnace 2 and that of the kiln furnace 3 issubjected to the combustion process. The deodorized gas is exhaustedfrom the flue 53 of the second smoke feeding portion 7 to the outside ofthe multifunctional disposal apparatus 1 or 1 a. Here, the dust filterdevice 46 of the dust filter portion 6 is not used. The opening/closingvalve 44 a of the gas flue 44 is closed and the opening/closing valve 45a of the gas flue 45 is opened so that the gas to be exhausted isbypassed from the smoke combustion portion 5 to the second smoke feedingportion 7.

In the indirect hot air drying process method of this example, since theodor is hardly generated at all, the deodorization step 134 may beomitted without driving the burner 37 of the first smoke feeding portion4, the burner 50 of the second smoke feeding portion 7, the smokecombustion portion 5 and the burner 79 of the smoke feeding portion 77.

“Disposal Object Fetch Process 135”

The object to be disposed such as the general garbage, the raw refuse orthe sludge can be taken out from the doors 16, 16 a and 18 uponcompletion of the drying process using the dry hot air. The raw refuseor the sludge accommodated in the kiln furnace 3 can be raked into thestorage chamber 33 to be accommodated or fetched.

The object of disposal taken out from the doors 16, 16 a and 18 or thestorage chamber 33 can be processed in any other process step, and thedisposal object obtained from the raw refuse or the sludge can be ofcourse used as fertilizers for a plow land or a fruit farm, a kitchengarden, a wadi and others or feeding stuffs for domestic animals such asa pig. Further, it can be accommodated in the dry combustion furnace 2and incinerated as a burnable garbage later.

Although the indirect hot air drying process method of this example isadvantageous in that the dry chamber is not odorized with the combustiongas because the air heating portion 8 is not driven, the heat efficiencyis low and only a medium temperature (approximately 70° C. to 400° C.)can be obtained. Therefore, it is necessary to select the generalgarbage, the raw refuse or the sludge to be dried which does not containheavy metals or toxic substances and is reusable and to input it intothe dry combustion furnace 2 or the kiln furnace 3.

FIG. 12 is a flowchart showing the method for drying the generalgarbage, the raw refuse or the sludge with the heated hot air by usingthe multifunctional disposal apparatus according to the presentinvention. The direct hot air drying process method of this exampledries the general garbage, the raw refuse or the sludge at a hightemperature (approximately 400° C. to 700° C.) without generating theodor.

“Refuse Input Process 141”

The raw refuse or the sludge is inputted into the first dry chamber 15from the input opening 13 a of the raw refuse input portion 13 providedto the dry combustion furnace 2 of the multifunctional disposalapparatus 1 or la shown in FIG. 2 or 6, and the general garbage isinputted from the input opening 14 a of the general garbage inputportion 14. The dry plate 15 a and the respective grating plates 15 c,15 e and 15 g are swiveled such that the raw refuse or the sludge can beevenly accommodated in the respective dry chambers 15, 15 b, 15 d and 15f.

The raw refuse or the sludge may be inputted from the doors 16 and 16 aof the dry combustion furnace 2 into the respective dry chambers 15, 15d and 15 f, or the raw refuse or the sludge may be inputted from theinput opening 14 a of the general garbage input portion 14 or the door18 into the combustion chamber 17. That is because the disposal bycombustion incineration is not performed in the combustion chamber inthis processing method.

Additionally, the raw refuse or the sludge may be inputted into the kilnfurnace 3 from the input opening 32 a of the refuse input portion 32provided to the kiln furnace 3 shown in FIG. 3, 6 or 7. That is becausethe disposal by dry combustion is not carried out in the kiln furnace 3in this processing method.

“Heating Step 142”

The heating burner 55 of the air drying portion 8 shown in FIG. 5 isignited, or the heat radiator 68 of the air drying portion 8 shown inFIG. 6 is driven. At the same time, the opening/closing valve 58 a ofthe air supplying tube 58 is opened, and the opening/closing valve 61 bof the air cooling tube 61 of the cooling tank portion 9 and theopening/closing valve 22 a of the air supplying tube 22 of the drycombustion furnace 2 are closed. The heating burner 20 a of the drycombustion furnace 2 is not driven.

The fresh air is taken from the air tube 56, and the fresh air is heatedby the heating burner 55 in the heating chamber 57. The heated airbecomes a hot air to be led into the dry combustion furnace 2 throughthe air supplying tube 58 and the air supplying tube 22. The hot air ledinto the dry combustion furnace 2 is heated to a high temperature ofapproximately 400° C. to 700° C. when led into the dry combustionfurnace 2.

“Suction Drying Step 143”

The blower 39 of the first smoke feeding portion 4 or the blower 52 ofthe second smoke feeding portion 7 shown in FIG. 3, 5 or 6 is driven, orthe blower 80 of the smoke feeding portion 77 shown in FIG. 7 is drivenso that the inside of the dry combustion furnace 2 and that of the kilnfurnace 3 form a vacuum. Any one or some of the respective blowers 39,52 and 80 may be driven or all of them may be driven.

When the inside of the dry combustion furnace 2 forms a vacuum, the hotair led into the dry combustion furnace 2 slowly passes the respectivedry chambers 15, 15 b, 15 d and 15 f and the combustion chamber 17 whilerepeating the circulation and dries the general garbage, the raw refuseor the sludge accommodated in these chambers 15, 15 b, 15 d, 15 f and 17with a hot air. Moreover, the hot air having passed through the drycombustion furnace 2 is led into the kiln furnace 3 via the smokeleading tube 29 to dry the raw refuse or sludge accommodated in the kilnfurnace 3 with a hot air. The kiln furnace 3 rotates the cylindricalbody 31 to perform drying.

“Deodorization Step 144”

The burner 37 of the first smoke feeding portion 4 or the burner 50 ofthe second smoke feeding portion 7 or the smoke combustion portion 5shown in FIG. 3, 4, 5 or 6 is driven, or the burner 79 of the smokefeeding portion 77 shown in FIG. 7 is driven so that the odor obtainedfrom the inside of the dry combustion furnace 2 and that of the kilnfurnace 3 is subjected to the combustion process. The deodorized gas isexhausted from the flue 53 of the second smoke feeding portion 7 to theoutside of the multifunctional disposal apparatus 1 or 1 a. Here, thedust filter device 46 of the dust filter portion 6 is not used. Theopening/closing valve 44 a of the gas flue 44 is closed and theopening/closing valve 45 a of the gas flue 45 is opened so that the gasto be exhausted is bypassed from the smoke combustion portion 5 to thesecond smoke feeding portion 7.

In the direct hot air drying process method of this example, since theodor is hardly generated at all, the deodorization step 134 may beomitted without driving the burner 37 of the first smoke feeding portion4, the burner 50 of the second smoke feeding portion 7, the smokecombustion portion 5 and the burner 79 of the smoke feeding portion 77.

“Disposal Object Fetch Step 145”

The incinerated ash is inputted to the crucible 74 mounted on the firebrick 74 b in the ash melting furnace 72 of the ash melting portion 7 ofthe multifunctional disposal apparatus 1 shown in FIG. 2.

“Heating Step 176”

The heating burner 73 set on the ahs melting portion 72 shown in FIG. 7is ignited to be heated to a high temperature of approximately 1300° C.to 1800° C. The high temperature is obtained by heat stored in thecrucible 74 and the inner wall of the crucible 74. That is, when bricksand the like are put around the crucible 74, it is possible to obtaineda high temperature by the effect of thermal storage. Setting bricks,casters and others around the crucible 74 can obtain a high temperature.Further, since a tip of the burner 73 is so set to face upwards, theflame spirally evenly heats the outer peripheral surface of the crucible74, thereby heating at a high temperature. Moreover, heating at a hightemperature is enabled by simultaneously incinerating the exhaust gasabsorbed and inflowing from the heating burner 73 and the kiln furnace 3and the incinerated ash.

At this time, when the exhaust gas absorbed and inflowing from the kilnfurnace 3 or the dry incineration furnace 2 is burned, the exhaust gasis reduced and the unburned gas is simultaneously burned. Therefore, thehigh temperature incineration can be performed by mixed combustion,which is advantageous in the countermeasure for the exhaust gas.

The cover 72 a is opened to see that glass, lava and others are moltenin the crucible 74, and they are then taken out.

“Cooling Step 179”

The incinerated ash taken out from the crucible 74 is cooled down byusing the cooling water or the air.

“Hardening Step 180”

When the meltage is hardened by applying the cooling water thereto orusing the air, it is hardened into a shape like an irregular marble.Such a hardened incinerated ash can be mixed into gravels for buildingmaterials or cement to be reused.

POSSIBILITY OF INDUSTRIAL UTILIZATION

Since the present invention has the structure described above, thefollowing advantages can be obtained. At first, taking usages afterincineration, incineration time and others into consideration,appropriate processes can be selected to be performed without generatingharmful substances.

At second, using the ejector quenching effect or the cold air drying cansuppress the odor and dioxins to the maximum level.

At third, the waste heat obtained from the combustion heat generated inthe combustion chamber can warm the hot air or stream, and the freezingmachine and the boiler can be operated by using the waste heat to beused for air conditioning of other facilities.

At fourth, when the contamination and the burned matter containingharmful substances such as dioxins or gases are injected, the oxidativecombustion and the smoke combustion can be simultaneously advanced,thereby pyrolyzing the harmful substances to be defused.

At fifth, when polymer-based substances or gases with which thecombustion object can be burned at a high temperature are injected andmixed to PCBs and others so that a temperature range reaches severalthousands ° C., the PCBs and others can be pyrolyzed in the reducedatmosphere to be defused.

At sixth, when the inputted combustion object defined in claims is mixedand incinerated, detoxication is enabled. Since this combustion systemcan incinerate pyrolyzing the dioxins and others without leavingunburned matters in the incinerated ash by combustion in the reducedatmosphere at a temperature of 450° C., dioxins and others can bepyrolyzed by mixing the residue containing a large amount of dioxins andothers in the conventional incinerated matter with the waste material,the conventional incinerated ash and the soil contamination (materialscontaining the dioxin) to be incinerated so that the oxidativecombustion and the smoke combustion are simultaneously carried out, thedioxins and other can be pyrolyzed. This incineration system does notproduces dioxins by pyrolysis in the combustion process and also doesnot produce dioxins in the incinerated ash because it is pyrolyzed inthe reduced atmosphere.

At seventh, even if the raw refuse, the sludge, the expandedpolystyrene, the polymer, the general garbage and others are mixed, theincombustible material can be dried or the polymer, the polystyrene andothers can be carbonized. Such processes can be stopped halfway, anddrying, carbonization and incineration can be finally carried outwithout restraint.

When the multifunctional disposal apparatus according to the presentinventions are set in parallel or in series, the operation as thecontinuous plant can be enabled.
